动态创建二维数组

#include <stdlib.h>
#include <string.h>
int **(int x, int y) {
    int **a = (int **) malloc(sizeof(int *) * x);
    int *b = (int *) malloc(sizeof(int) * y);
    int *c = (int *) malloc(sizeof(int) * y);
    b[2] = 100;
    a[0] = b;
    a[1] = c;
    return a;
}
int main(int argc, char **argv) {
    int x = 2;
    int y = 10;
    int **a = createArr(x, y);
    printf("a = %d n", a[0][2]);
    for (int i = 0; i < x; i++) { // 释放指针
        free(a[i]);
    }
    free(a); // 释放指针
    return 0;
}
